OF DAYTON,

OHIO, A. CORPORATION OF DELAWARE REBIGERATING APPARATUS Application filed April 30, 1930. Serial No. 448,581.

This invention relates to mechanical refrigerators and more particularly to the type ofrefrigerators having a refrigeratin element located within a refrigerator ca inet, and connected with refrigerant circulating ap aratus.

Another object is to support the refriger-' ant circulating apparatus on a wall of the refrigerator cabinet, and to provide for the ready removability of said apparatus through a door opening of the food compartment of saidcabinet.

Another object is to provide an improved refrigerator cabinet of the type in which the food compartment is located in the upper portion of-the cabinet and the machinery orv refrigerant circulating element is located below the food compartment and is connected to a refrigerating element or cooling unit in the food compartment, and in which the machinery and cooling unit may be removed from or installed in the cabinet Without disconnecting one from the other.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings, wherein a preferred form of the invention is clearly shown.

In the drawings:

Fig. 2 is a vertical view in, cross section taken along the line 22 of Fig. 1;

Fig. 3 is a front view in'elevation of a refrigerator embodying features of the invention;

Fig. 5 is a longitudinal view in cross sectiontaken along the line 55 of Fig. l; Fig. 6 is a View similar to the view shown in Fig. 5 with another form of refrigerating element installation;

Fig. 7 is a View of the apparatus as mounted for transportation, and

Fig. 8 is a view of a modified form of construction of the cabinet lining.

Referring to the drawings, there is shown a cabinet comprising a food or cooling compartment 21 located preferably in the upper portion of the cabinet. A. refrigerant circulating element, designated in general by the numeral 25 may be located below and depends from a Wall of said cooling compartment, and if desired, the element 25 may be enclosed in a compartment 22. The element 25 is adapted to circulate refrigerant such as sulphur dioxide to a refrigerating element 27 disposed within the cooling compartment. The cabinet is also provided with an inner lining 28, insulation 28a disposed between said lining and an outer covering 29. The

cooling compartment is provided with the usual opening 30 closed by a door 31. The cabinet is also provided with an opening 33 in the lower portion thereof, which opening is closed by closure means or a supporting base 35 which forms a bottom Wall of the cooling compartment of 1 the refrigerator. The cabinet is also provided with a plurality of ready removable shelves 36 for supporting articles to be refrigerated.

Referring more in detail to the drawings and particularly to Figs. 2 and 5, the refrigerant circulating element 25 as shown may comprise in general a compressor 40, driving motor 41, and an air cooled condenser 42 which is cooled by a fan 45 connected to the shaft of motor 41. The compressor is oper atively connected to the motor bybelt 47. The compressor delivers the compressed re frigerant to the condenser wherein it is liquefied and from which it is delivered to a receiver 50. The liquid refrigerant is delivered from the receiver to the refrigerating element 27 through pipe 52, and returned to the compressor through pipe 53.

The refrigerant circulating element 25 depends from and is supported by the wall 35. and for instance, the element 25 may be supported by the bracket means 56 secured to the wall 35 by screws 57. Depending from and secured to the wall 35 is also an enclosure 60 which encloses the circulating element or machinery or apparatus. The enclosure 60 is provided with a plurality of louvers 62, in one side thereof, preferably the rear side, to permit air to be circulated within said enclosure by the fan 45 for cooling the motor, compressor and condenser.

As shown in the drawings, the wall 35 may comprise a wooden frame 70, insulating material 71 enclosed by said frame, a supporting plate 73 and a top plate 74. The top plate 74 may be provided with an upwardly directed flange 75 to prevent moisture from entering the cabinet. The wall 35 is ada ted to be supported on the framework 78 o the cabinet 20. A gasket seal 79 may be secured to the underside of the wall 35 to thus effectually seal the cabinet about the opening 33.

If desired, the element 27 may be mounted on the wall 35b means of brackets 80. Also, if desired, the plpes 52 and 53 may be enclosed by a standpipe 82 mounted on the wall 35.

By the present arrangement the cooling unit and machinery may be removed from or installed in the cabinet without disconnecting one from the other. As a specific embodiment, the elements 25, 27 and wall 35 may be removed as a unit through the door opening 30. In order to remove this entire unit from the cabinet all that is necessary is to raise said unit upwardly and then remove same through the opening 30. If desired, the wall 35 may be arranged to be slid horizontally out of the cabinet. This may be accomplished by making the lower door sill 7 8a of lhe cabinet removable in order to carry with it, or to permit the removal of the wall 35 which may carry the entire refrigerating system as a unit.

As shown in Fig. 6 the refrigerating element 27 may be suspended from the top wall of the cabinet. In this particular installation the pipes 52 and 53 may be concealed by plate 85. This arrangement also permits the removal of the elements 25, 27 and the wall 35 and the enclosure 60 as a unit through the opening 30. In order to be removed as a unit neither the refrigerating element nor the refrigerant circulating element need be mounted on any particular support so long as the disconnection of the refrigerant circulating pipe or pipes is not necessary during the removal or installation.

r Fig. 7 shows the apparatus as arranged for transportation either before the original installation or after removal from the cabinet to be ship )ed for repairs. The apparatus shown in the type shown in Fig. 6. Thus the apparatus is provided with flexible pipes of sufficient length to permit the refrigerating element to be sus ended from the top wall of the cabinet. n making the installation in the cabinet the brackets 90 and clamps 92 may be removed. The apparatus shown in Fi 4 may be shipped and installed in a cabinet as shown.

In Fig. 8 there is shown a modified form of construction of the lining 28. In this particular embodiment the lining 28 is provided with an inwardly directed flange 94 having an upwardly directed flange 95 to thus form a trough. This flange 94 is provided to prevent moisture from entering the framework of the cabinet. If desired, a drain pipe 97 may be provided for the trough.

V From the foregoing it will be noted that I have provided a refrigerator comprising two ma or units, namely, the cabinet 20 and a unit carrying the refrigerating system and comprising the elements 25, 27 and the wall 35, and that said system may be readily and easily removed from or inserted into said cabinet. It will also be noted that said system preferably may be removed from or inserted into said cabinet through the door opening of the food compartment.
